Abstract

The invention discloses a transparent easily-torn sealing film and a manufacturing method thereof. The transparent easily-torn sealing film comprises a matrix, wherein the matrix comprises a printing layer, an adhesive layer, a blocking layer and a heat seal layer which are sequentially connected; the printing layer is a polyethylene glycol terephthalate film layer, and the blocking layer is a polyethylene glycol terephthalate film layer. The manufacturing method of the transparent easily-torn sealing film comprises the following steps: (1) manufacturing a blank film; and (2) carrying out ripening. After being subjected to hot seal with a metal cover, the transparent easily-torn sealing film is easy to tear, safe, sanitary, transparent and visual, and packaged objects are conveniently taken out; and safety hazards in the prior art that aluminum scraps fall into mill powder and fingers are scratched by aluminum foils are eliminated.

Description

technical field [0001] The invention relates to the technical field of flexible packaging, in particular to a transparent easy-tear lid sealing film and a manufacturing method thereof. Background technique [0002] "Food is the most important thing for the people, and food safety is the first." Food safety affects everyone's daily life and health. At present, the traditional milk powder can packaging in China is not easy to open, and it is inconvenient to use the contents of the package. [0003] In traditional canned milk powder packaging, the bottle cap is composed of three parts: an embedded aluminum foil, an annular ring and an iron cover. When opening, the outer cover should be pried off first, and then the aluminum foil should be cut with a sharp object before the milk powder can be used. Cut the aluminum foil There are often aluminum chips falling into the milk powder, which is a health hazard. In addition, if the aluminum foil is cut, it will remain on the edge of th...
